  • The naval variant of the Light Combat Aircraft (LCA) Tejas has made a successful short arrested landing on the Shore Based Test Facility (SBTF) in Goa.
  • The LCA made its maiden successful trap on the SBTF with the tail hook of the aircraft connecting with the arrestor wire on the deck and coming to halt within a short distance.

Naval Variant of LCA

  • The LCA (Navy) is the naval version of indigenously developed Tejas fighter aircraft being developed for the Indian Air Force.
  • The naval LCA made its maiden flight in April 2012 and two prototypes have been flying as part of the development.
  • The first prototype (NP1) made a successful first flight from the SBTF in 2014.
  • The naval version of the LCA is designed with stronger landing gear to absorb the force exerted by the ski jump ramp during take-off allowing it to be airborne from a much shorter runway on the deck of the aircraft carrier.
  • Its special flight control law mode allows hands-free take-off, reducing the pilot’s workload as the aircraft leaps from the ramp and automatically puts the aircraft in an ascending trajectory.

What is Arrested landing?

  • Arrested landing means to rapidly decelerate an aircraft as it lands.
  • An “arrested landing” on the deck of an aircraft carrier is a feat achieved only by a handful of fighter jets developed in the US, Russia, UK, France and China.


  • In December 2016, then Navy Chief stated that the LCA in the present formdoes not meet the carrier capability which is required by the Navy” but added that they would continue to support the development programme.
  • The current weight of the naval LCA with the underpowered engine did not allow it to fly from a carrier.
  • The successful short arrested landing on the Shore Based Test Facility (SBTF) is seen as a major step forward as it tests modifications that will allow the naval variant of the Tejas to eventually operate from an aircraft carrier.
  • Indian Navy needs several fighter jets for its future aircraft carriers, including INS Vikrant, which is under advanced stages of construction.

About LCA Tejas

  • The Light Combat Aircraft (LCA) programme, which began in the 1980s to replace India’s ageing MiG-21 fighters.
  • In 2003, the LCA was officially named “Tejas”.
  • It is an Indian single-engine, delta wing, multirole light fighter designed by the Aeronautical Development Agency (ADA) and Hindustan Aeronautics Limited (HAL) for the Indian Air Force and Indian Navy.
  • It is an indigenous light weight, multi role supersonic aircraft developed in both fighter and trainer
  • Advanced materials like composites are used in the manufacture of the Tejas to reduce weight and increase the component life.
  • It is designed to carry a veritable plethora of air-to-air, air-to- surface, precision guided and standoff weaponry.

  • Union Minister for Communications, Electronics & Information Technology and Law & Justice, Ravi Shankar Prasad has unveiled the portal,, wherein the customer is required to report the lost phone or theft after filing a police complaint.
  • The project has started on a pilot basis in Maharashtra and later it will be implemented across the country.


It aims to reduce the resale of lost/stolen phones by blocking the IMEI number. This move will also prevent the mobile phones to duplicate the IMEIs across the network.

How will it work?

  • Each mobile phone has a 15 digit unique indemnification number International Mobile Equipment Identity (IMEI) number.
  • Whenever a user makes a call, the call record shows phone number of the caller and IMEI number of the handset from which the call has been made.
  • The unique number of mobile devices is allocated by global industry body GSMA and bodies authorised by it.
  • When the mobile is stolen or lost, the concerned person has to lodge an FIR and inform Department of Telecom (DoT).
  • DoT will block the reported lost/stolen phone across the network which will prevent the reuse of the phone.
  • If anyone tries to use the same device, the telecom service provider will identify the new user.
  • The service provider will provide information to police to trace the lost/stolen mobile phone.

Central Equipment Identity Register (CEIR)

  • A large number of mobile phones have duplicate IMEIs making it challenging for the authorities to block such devices.
  • The reported mobile phone will be blocked across networks and all existing mobile numbers with the IMEI will be put in an override list.
  • If such IMEI is blocked, a large number of mobile phones will get blocked being handsets with same IMEI causing inconvenience to many genuine customers.
  • Thus, there is a need to eliminate duplicate/fake IMEI mobile phones from the network.
  • To deal with the associated problems, an indigenous solution has been developed by C-DOT, a research and development unit of the Department of Telecommunications (DOT).
  • Since 2017, DOT has been working on developing the Central Equipment Identity Register (CEIR), which will be a database of billions of IMEIs in India.
  • The CEIR will additionally be able to access the GSMA’s worldwide IMEI database and compare IMEI numbers to track down counterfeit handsets.
  • This would ensure international cooperation in matters of handset theft.

VSAT solutions provider Nelco, a Tata enterprise announced the launch of maritime communication services, becoming India’s first company to provide broadband services to the maritime sector.

About the Project

  • Nelco, through global partnerships and infrastructure, including transponder capacity on the satellite of ISRO and service portfolio, will help energy, cargo and cruise vessels by enhancing operational efficiency.
  • The in-flight and maritime communications (IFMC) licence has not only enabled connectivity for on-board users on ships but also brings operational efficiencies for shipping companies which were less evolved until now.
  • Maritime Connectivity will enable high-end support to those in sea by providing access to Voice, Data and Video services while traveling on sailing vessels, cruise liners, ships in India, using satellite technology.

Paleontologists have identified a new species, named Cryodrakon boreas, and declared that it could be one of the largest flying animals. With a wingspan of over 10 metres, it is believed to have flown over the heads of dinosaurs. Its remains were discovered 30 years ago from the Dinosaur Park Formation located in Alberta, Canada. Then, palaeontologists had assumed that it belonged to an already known species of pterosaur, Quetzalcoatlus. A new study by reseachers from the Queen Mary University of London has concluded that the remains belong to a new species, which is also the first pterosaur to be discovered in Canada.


Union Minister for Skill Development and Entrepreneurship (MSDE) has laid the foundation stone of Indian Institute of Skills (IIS) at Mumbai. IIS aims to provide skill training in highly specialized areas to students who want to pursue technical education after completing Class X and Class XII, making them employable and industry ready for the New India and the global market. The vision behind setting up IIS was to build world-class skill training centres in line with reputed educational institutes like Indian Institute of Technology (IIT) and Indian Institution of Management (IIM), with first-hand learning facilities from internationally renowned existing skill institutions. The Union Cabinet had given its nod to set up Indian Institute of Skills (IISs) in three locations of the country — Mumbai, Ahmedabad and Kanpur, to give wings to the Skill India Mission. These institutes will be constructed & operated on a PPP (Public-Private Partnership) model and in not-for-profit basis. Tata Education Development Trust (TEDT) was selected as the private partner for setting up IIS at NSTI campus in Mumbai through a competitive bidding process.


The Defence Acquisition Council (DAC), chaired by Defence Minister Rajnath Singh has approved indigenous development of ammunition for the Army’s T-72 and T-90 tanks worth approximately ₹2,000 crores, which would enhance the enemy armour penetration capability. The DAC has also approved procurement of Defence Research and Development Organisation (DRDO) developed and Industry manufactured Mechanical Mine Layer (Self Propelled) to improve automated mine laying capability of the Indian Army.
